Abstract
The invention provides a transit multicast transmission method and a system thereof, a transit selection server, a transit node and a terminal. A first terminal sends a transit selection request to the transit selection server. The transit selection server determines a plurality of second terminals which are about to communicate with the first terminal according to transit selection request, determines a multicast transit node corresponding to the at least two second terminals and sends transit multicast notifications to the first terminal and the multicast transit node respectively. The first terminal sends one portion of data to the multicast transit node. The multicast transit node copies the data from the first terminal and carries out the multicast to the at least two second terminals. According to the invention, the terminal only needs to send the one portion of data to the multicast transit node and the node copies the data and carries out the multicast to the plurality of terminals so as to increase transmission efficiency.
Description
Technical field
The application relates to the communication technology, relates more specifically to transfer multicast transmission method, system, transfer selection server, transit node and terminal.
Background technology
Multicasting technology is meant the network technology that allows one or more terminals (source terminal) data packet transmission of identical data to be arrived a plurality of terminals.Multicast is one of effective ways of saving the network bandwidth as some communication to multiple spot.At present, multicasting technology is widely used in aspects such as network audio/video broadcasting, AOD/VOD, the network teleconference, multimedia remote education, " push " technology (like stock market etc.) and reality-virtualizing game.
In addition, the route of data is all transmitted according to default route usually in the communication, but because carrier policy or default route are congested, can cause default route possibly not be best path, thereby influences the quality of real time business such as speech business.The data relay technology is the quality assurance technology that adopts usually in the communication system.On communication link, add transferring equipment and change default route, data are transferred to next stage equipment through trunking.Adopt the data relaying, and combine network topological information, can reduce data transmission delay, and can reduce packet loss and shake that network congestion brings.
At present, the multicasting technology based on transfer has also obtained using widely.Fig. 1 shows in the prior art sketch map based on the multicast transmission system of transfer.In the prior art; When source end UE1 will be when destination UE2-UE5 sends multi-case data; Source end UE1 selects server to send transfer to transfer and selects request; Wherein, transfer selects request to comprise that source end UE1 will be to the request of destination UE2-UE5 multi-case data, also can comprise with the address of destination UE2-UE5.Transfer is selected server to select request to be respectively destination UE2-UE5 according to transfer and is selected corresponding transit node, and for example destination UE2 is corresponding to transit node RN-1, and UE3 is corresponding to RN-2, and UE4 is corresponding to RN-2, and UE5 is corresponding to RN-3.Transfer selects server to send the transfer notice to source end and each transit node, and the source end is sent to each transit node with data, is forwarded to corresponding terminal by transit node.
Yet; According to transfer multicasting method of the prior art, for realizing sending data to destination UE2-UE5, the source end will send a piece of data respectively to transit node RN-1 and RN-3; Send two piece of data to RN-2; Promptly need take 4 UE-RN data transfer path resources, therefore, cause the waste of network transmission resource.
